Provakar joined the group in 2018 as a Ph.D. thesis student. He got his bachelors and masters degrees in physics from St. Xavier’s College, Kolkata and Indian Institute of Technology (IIT), Madras respectively. In the first one and a half years after joining the group, Provakar worked on several simulation projects which helped with the preparation for the running of several Super BigBite Spectrometer (SBS) collaboration experiments, as well as the testing of photomultiplier tubes for the Ring Imaging Cherenkov Detector for SBS. Then in January 2021, after finishing all required classes in the Ph.D. program, he relocated to Virginia and got involved in hardware work at Jefferson Lab. Provakar took a lead role in the testing, commissioning and calibration of the electron calorimeter, A.K.A the BigBite Calorimeter or BBCAL, which is an integral part of the electron arm spectrometer that is going to be used in almost all SBS experiments, scheduled to run in Jefferson Lab’s Hall A. One of these several SBS experiments is E12-09-019, which aims to measure the neutron’s magnetic form factor, GMn, up to Q^2=13.6 GeV^2. The data taking of E12-09-019 was finished recently and, as a thesis student on E12-09-019, Provakar’s primary focus right now is leading the analysis of the data collected during the GMN run from Fall 2021-February 2022. Provakar defended his doctoral dissertation in September 2024 and will continue in the group as a postdoctoral research associate.

Rupesh was a postdoctoral research associate in the group and the SBS collaboration from August 2022-February 2023. He completed his masters degree in Physics from Tribhuvan International University, Nepal. He received his PhD degree (Aug 2016 – July 2022) from Florida International University where he was part of the major Hall D experiment at Jefferson Lab,
called the GlueX (Gluonic Excitation). His PhD work was the analysis of the GlueX data to search for the
π¹(1600), the lightest exotic hybrid meson predicted by lattice QCD and also seen in previous pion scattering
experiments like COMPASS. During his PhD he was also responsible for timing calibration and monitoring of
the GlueX Start Counter detector for several experiments conducted in Hall D like GlueX, PrimEx and Short-
Range Correlation experiments. His current focus is to contribute to the development of the SBS software
for event reconstruction, data analysis and Monte-Carlo simulation in the SBS experiments. He is also
expected to contribute to the preparation and installation of the SBS RICH detector for the upcoming SIDIS
experiment in Hall A at Jefferson Lab. Rupesh is currently in medical physics.

Dr. Eric Fuchey was a group member from 2016-2022 Dr. Fuchey received his Ph.D. from the Université Blaise Pascal in Clermont-Ferrand, France in 2010. His dissertation research focused on the exclusive electroproduction of neutral pions in the hard-scattering regime in Jefferson Lab’s Hall A. These results were published in Physical Review C in 2011. Prior to joining UConn, he previously held postdoctoral research appointments at Temple University and at the CEA Saclay. Dr. Fuchey is the author or co-author of more than fifty refereed journal publications.  He played a lead role in the development of the Monte Carlo simulation, event reconstruction and data analysis software for the Super BigBite Spectrometer (SBS) family of experiments that started in 2021 in Hall A at Jefferson Lab. He is also the cospokesperson and contact person of experiment E12-20-010 to precisely measure the so-called “Rosenbluth Slope” in elastic electron-neutron scattering at a Q² of 4.5 GeV², that collected data in early 2022 that are currently under analysis. From 2022-2023, Eric worked at Mississippi State University on the SpinQuest experiment at Fermilab. Since 2023, Eric has returned to the SBS Collaboration with the College of William and Mary, where he continues to play a lead role in the SBS software effort and lead the analysis of the SBS GMN/nTPE datasets.

Freddy was a Ph.D. thesis student in the group from 2014-2018, and recently completed his dissertation research extracting the neutron electromagnetic form factor ratio from the data collected by Jefferson Lab experiment E02-013. Freddy was also an active participant and strong contributor to our efforts in Monte Carlo simulation, software development, and detector preparation for the Super BigBite Spectrometer (SBS) family of experiments. Freddy defended his thesis in January 2019. After completing the Insight Data Science postdoctoral fellowship program in New York City during the spring of 2019, Freddy started a Data Scientist position at the Johns Hopkins University Applied Physics Laboratory.

Christopher Oldham was an undergraduate research assistant in the group during the fall of 2017 and the summer of 2018. He worked on the measurement of the absolute quantum efficiency of the photomultiplier tubes to be used in the RICH detector for the SBS.

Brenna Robertson was an undergraduate research assistant in the group during the summer of 2018. She worked on the measurement of the absolute quantum efficiency of the photomultiplier tubes to be used in the RICH detector for the SBS.

Sebastian joined the group in 2018 as a PhD student interested in experimental nuclear
physics. He earned his Bachelor’s degree double-majoring in Physics and Philosophy from the
University of Colorado, Boulder in 2014 where he graduated Magna cum Laude for his work in
the Nagle experimental nuclear group and sPHENIX located at RHIC, Brookhaven National Lab.
Between undergraduate and graduate studies (2014-2018), Sebastian worked in plastics and
metal injection molding and manufacturing as a Quality Engineer and Analyst specializing in
quality control systems.

Sebastian’s primary work in the Puckett group includes Monte-Carlo simulations, installation,
commissioning, experimental running, and data analysis for the GMn experiment (precision measurement of the
neutron magnetic form factor at Jefferson National Laboratory – part of the Super BigBite (SBS)
family of experiments). Additionally, Sebastian has worked on quantum efficiency
measurements characterizing the Ring Imaging CHerenkov (RICH) detector and is a primary
expert for the Hadronic Calorimeter detector and subsystem (HCal) employed throughout SBS.
Beyond professional interests, Sebastian is an accomplished hiker and cook and enjoys both.
